Speaker Bracket

       This article describes a snap-fit mounting mechanism for
a speaker bracket to a circuit card.

      In the drawings, Fig. 1 is a partially exploded view of the
complete assembly showing the location and associated parts of the
information panel.  Fig. 2 is top view of the speaker bracket.  The
broken line designates the speaker magnet diameter.  Fig. 3 is a side
view of the speaker bracket.  Fig. 4 is a partial cross-section of
the support ring across A-A in Fig. 2.

      The speaker bracket described in this article is molded from a
blend of polycarbonate/abs which provides an excellent flexural
modulus and strength factor for the four major functions of this

      The primary function of the speaker bracket B (Fig. 1) is
defined as the four radii (see Fig. 2) which encircle a central point
for speaker retention.  Each radii is chamfered as shown at J which
aids in aligning the speaker magnet about the central point as it is
inserted.  The vectors that are numbered 1-8 illustrate the
deflection in plastic as the speaker A is inserted.  Once the speaker
A has been fully inserted into the opening, eight equal pressure
points are created between the speaker magnet and the outer edges of
each deflecting radii.  These radii have a U-shaped support leg E
molded to them (see Fig. 3) to provide the secondary function of the
speaker bracket B.

      Referring again to Fig. 1, the speaker bracket B is snapped
into place by aligning four live snaps F in position over four
openings in the information panel and applying 18 pounds of pressure
to the...
